TWIN-HEAD ROTARY ENGINE.

Specication of Letters Patent.

Patented Feb. 27, `1906.

Application filed August 5,1905- Serial No. 272,927.

To all whom it may concern:

Be it known that I, HOMER ARTHUR KING, a citizen of the United States,residing'at Colton, in the county of San Bernardino and State ofCalifornia, have invented a new and useful Rotary Engine, of which thefollowing is a clear and exact description.

My invention relates to improvements in rotary engines in which I employtrailing cylinder-heads or cylinder-head in an annular cylinder. y

The object of my invention is to supply a simple and safe substituteinstead of those complicated dangerous cylinder-heads which enter andare withdrawn 'from the cylinder to let the pistons pass. I attain thisobject and increased speed with economy of motive Huid and weight bymechanism illustrated in the accom anying drawings, making a part ofthis spec' cation, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a vertical section of the inner exhaust side of my engine.Fig. 2 is an elevation of the piston-dlsk. Fig. 3 is a vertical sectionshowing the inner part of the side of the annular cylinder of my enginewith ports for admitting the motive fluid and with Fig. 2 in place, butwith two cylinderheads F F locked to the cylinder and pistons E E drivenforward as if the parts were all in place and in operation. Fig. 4 is avertical section of the annular cylinder corresponding to Fig. 1,'butwith more exhaust-openings H and H. Fig. 5 is an elevation correspondingto Fig. 2, but with this central disk havin more twin heads E F. sectioncorresponding to Fig. 3, but with more twin pistons and cylinder-headsand with two cylinder-heads F F just unlocked and hastening to theirnormal place near E. Fig. 7 is an elevation of the exhaust-regulator Lshown in Fig. 8, but probably will not be needed. Fig. 8 is a verticalcross-section of my engine with all the parts in place, taken in linethrough F F. Fig. 9 is an elevation of the cut-off L, with slots tocorrespond with the number of pistons in style Fig. 6. Fig. 10 is across-section of one of the cylinderheads F, taken in the line where thetwo halves of the cylinder are united by bolts through the periphery.Fig. 11 is a cross-section of one of the pistons E, taken in line ofcrosssection of the annular cylinder;

The letter A refers to the exhaust side of Fig. 6 is a vertica theannular cylinder, through which the used motive fluid escapes byport-holes H and H2.

B refers to the side where the motive iiuid is Iadmitted throughport-holes I.

C designates the disk to which pistons E are secured by bolt E.

D is the opening for the shaft D.

F is the trailing cylinder-head connected by wire J to piston'E, eachend secured in a cavity bringing E and F nearer together, and F is thefiexible face which yields to the pressure of the motive fluid and locksbolts F2 in depressions in the cylinder at desired points.

G is the outside casing forming the exhaustchest with port-hole, and Gis the casing forming the motive-fluid chest.

K is a depression near the periphery of the flange for packing.

N indicates the usual collar-ring with an opening for contraction orexpansion.

When the parts are all in place and the motive fluid is admited at I Ibetween the heads E F E F, F F are locked by pressure on faces F F',forcing bolts F2 F2 into depressions in the cylinder and forcing pistonsE E forward, first by direct pressure while slots M M are over I I andwhen covered then by expansion, and before E E reach exhausts H H, Fig.6, two other pistons have passed two other port-holes I I, and directpressure is on again. When the used motive fluid escapes at H H2, anyremaining escapes at ports H giving constant pressure; but when styleFigs. l, 2, and 3 is used and the expansion is caused by explosion, bothE and F are allowed to pass I I ere the sparks cause the explosion. Themomentum carries the pistons forward, so that constant pressure is notneeded 5 but it can be had even in this style by arranging two or moreengines on one shaft or axle.

The heads E and F may be'connected by two or more coiled-wire springs,or one of less coiled diameter may be used in one of larger diameter, orany other elastic connection may be used.

What I claim as my invention, and to secure by Letters Patent, is*

l. One or more pistons and trailing cylinder-heads, within an annularcylinder of a rotary engine, connected to a disk and shaft desire4revolved by the pressure of a motive fluid.

2. One or more pistons and trailing cylinder-heads having a cavity ineach of the latter or in all, in which the ends of an elastic [OOl IIO

connection are secured, and a disk to which l tion to the piston, saidpiston being secured. the pistons are secured Within an annular to adisk revolving a shaft by the pressure of cyllnder of a rotary enginerevolving a shaft 1 a motive fluid.

by pressure of a motive luid.

3. Within the annular cylinder of a rotary engine, a piston, a trailingcylinder-head having elastic connection therewith, with bolts movable bythe pressure oi' a motive fluid, automatically locking the cylinder-headto the cylinder, and automatically unlocking it by the diminishingpressure and elastic connec- In testimony whereof I have signed my 1.5name to this speciiication in the presence of two subscribing witnesses.
